Alec Baldwin says he’s staying on ’30 Rock’… and that the show is ending next season

Alec Baldwin has been on the brink of leaving 30 Rock since basically the beginning of 30 Rock.
Playing Jack Donaghy revitalized Baldwin’s career — and helped to
define the resurrection-through-self-deprecation second-act playbook of
our modern reboot era. But the actor has regularly expressed an interest
in leaving the show — usually in the winter, which either proves that
he enjoys negotiations with NBC or that he suffers from a nasty case of
Seasonal Affective Disorder.

Most recently, Baldwin had tweeted “I think I’m leaving NBC just in time” in the context of a rant about the Today show, which had sent cameras to his apartment. However, Baldwin now tells the Associated Press that “time” is relative: He’s sticking with 30 Rock through next season.
